If the subject report could not be filed without unreasonable effort or expense and the registrant seeks relief pursuant to Rule 12b-25(b), the following should be completed. (Check box if appropriate)

¨	(a)	The reason described in reasonable detail in Part III of this form could not be eliminated without unreasonable effort or expense
	(b)	The subject annual report, semi-annual report, transition report on Form 10-K, Form 20-F, Form 11-K, Form N-SAR or Form N-CSR, or portion thereof, will be filed on or before the fifteenth calendar day following the prescribed due date; or the subject quarterly report or transition report on Form 10-Q or subject distribution report on Form 10-D, or portion thereof, will be filed on or before the fifth calendar day following the prescribed due date; and
	(c)	The accountant’s statement or other exhibit required by Rule 12b-25(c) has been attached if applicable.

PART III — NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

The Form 11-K, which is the subject of this Form 12b-25, is being filed in order to report the information required of the Capital Accumulation Plan of The Chubb Corporation (the “Plan”). The Plan is unable to file its Form 11-K on a timely basis, without unreasonable effort or expense, because the audit of the financial statements has not yet been completed. The predecessor auditor of the Plan’s financial statements recently discovered that they were not able to act as auditor this year due to independence conflicts stemming from Chubb Limited’s acquisition of The Chubb Corporation. As of the date of this filing, we have engaged another independent auditor and the Plan will file the Form 11-K promptly following completion of the audit of the Plan’s financial statements.
